The Sirius Black strain originates from Oregon and was developed by the Oregon Breeders Group. Its genetic lineage has not been publicly disclosed, adding to the mystery surrounding this deep-purple strain. What is well documented is its striking color, rich grape-and-berry aroma, and indica-dominant character.
According to Oregon Breeders Group co-founder Wade Preble, the Sirius Black available today is an homage to a dark-purple indica-like plant the group grew in the late 1970s and early 1980s. The later Sirius Black project focused on developing a modern strain with naturally vivid purple flowers, strong aroma, and satisfying quality.
The exact genetic lineage of the Sirius Black strain remains undisclosed. Oregon Breeders Group has not publicly released its parentage, so claimed links to specific purple strains should be treated as unconfirmed unless referring to a separate commercial seedbank version.
The Sirius Black strain is especially known for its visually striking appearance. Its dense buds can display deep purple tones that appear almost black, contrasting with bright orange pistils and frosty trichomes. Importantly, Oregon Breeders Group has explained that Sirius Black develops its purple coloration naturally through its genetics rather than requiring cold stress.
Reported Sirius Black THC levels vary by source and commercial seed version. Major strain databases list approximately 15–22% THC, while some specific feminized seed versions advertise levels reaching up to 25%. Because potency can vary depending on genetics, phenotype, and cultivation conditions, users should always start low and proceed carefully. If you want to test harvested cannabis, the miraculix THC/CBD-QTest available at Sirius can be used to estimate THC and CBD concentrations.
The Sirius Black strain is often associated with relaxing effects, but its aroma is just as memorable. Its rich scent profile is commonly described as sweet grape and berry with earthy undertones. The next sections break down its taste, reported terpenes, effects, and signature dark-purple appearance.
The aromatic profile of the Sirius Black strain is equally remarkable. It features a complex bouquet of sweet grape and subtle berry notes, underscored by a rich, earthy base that ties the scents together. This strain delivers a flavor that is both sweet and tart, creating an enjoyable and memorable experience. The taste lingers pleasantly, leaving a fruity aftertaste that many cannabis enthusiasts appreciate.
To get the full flavor out of Sirius Black, we highly recommend skipping the tobacco and smoking it pure. Even better, use a good quality dry herb vaporizer.
The reported terpene profile of Sirius Black includes myrcene, limonene, and caryophyllene, which complement its sweet grape, berry, and earthy aromatic character.
Visually, the Sirius Black strain lives up to its name. Its buds are known for their vibrant deep-purple color, which can appear almost black, creating a striking contrast with the bright orange pistils. The dense flowers are often covered in a frosty layer of trichomes, giving them a shimmering, resin-rich appearance.

Growing the Sirius Black weed strain requires attention to light, airflow, nutrition, and general plant health.
Because detailed grow specifications vary between commercial seed versions, the information below should be treated as general guidance rather than universal data for every Sirius Black plant.
Flowering time and yield information for Sirius Black varies depending on the commercial seed version. Some feminized versions list approximately 8–10 weeks of flowering, with indoor yields reaching up to around 500 g/m² and outdoor yields reaching up to around 900 g per plant under optimal conditions. In Sirius’ online Growshop, you can find grow tents, cannabis grow lights, weed fertilizers, and other essentials for indoor and outdoor growing.
Unlike many purple strains, Sirius Black is known for developing its vivid purple coloration naturally through its genetics. Oregon Breeders Group co-founder Wade Preble explained that outdoor plants can begin turning purple in August even during very warm weather. For this reason, growers should not cold-stress Sirius Black simply to deepen its color, as extreme cold can negatively affect plant health and final quality. Sirius Black is known for its naturally deep-purple flowers, although the exact appearance of individual plants can vary depending on genetics, phenotype, and cultivation conditions.
